Title: Running apparatus for tape
Inventor: IWATA TOKUYA
IPC: G11B15/61
Filed: 1992-11-25
Abstract: PURPOSE:To optimize the regulating force for a tape, to securely run the tape stably and to prevent the damage of the tape edge by changing the regulating height of the tape by a tape guide in accordance with the winding diameter of a reel. CONSTITUTION:The regulating force at a variable guide post 107 is proportional to the regulating height when the tension of a tape is constant. In the case where the winding diameter of a tape roll 24 is small, a reflecting photosensor 31 detects that the rotating speed of a reel stage 22 is fast, and the impressing voltage to a laminated piezoelectric element 42 is decreased by a voltage variable controlling circuit 120. As a result of this, the element 42 shrinks, and a tape guide attached at the upper end of tone element 42 moves downward in accordance with the movement of the element 42. If the winding diameter of the roll 24 is large, the impressing voltage from the circuit 120 is increased because of the low rotating speed of the stage 22, thereby the element 42 expands. Consequently, the tape guide moves upward and the height of a flange 41 regulating a tape 1 is increased, and therefore the regulating force is increased and running of the tape is thus stabilized.

CONSTITUTION:A retiming circuit 13 outputs a retiming signal (j) by retiming an output signal (h) of a 1/2 frequency divider circuit 11 at the leading edge of an output signal (i) of a 1/2 frequency divider circuit 12 and a retiming circuit 14 outputs a retiming signal (k) by retiming an output signal (j) of a retiming circuit 13 at the leading edge of an output signal (i) of a 1/2 frequency divider circuit 12. Then a logic circuit 15 exclusively ORs the signals j, k and outputs a resulting alarm signal l. Thus, out of synchronism is detected at the time of slipping, the edge dispersion in the out of synchronism detection point is decreased and circuit applied to a phase synchronizing oscillator whose phase comparison frequency is high.

Title: Swash plate supporting structure of swash plate type variable piston pump motor
Inventor: TAKEUCHI MASAMITSU
IPC: F03C1/30
Filed: 1991-11-05
Abstract: PURPOSE:To make it possible to move a swash plate abliquely and to prevent a floating-up of the swash plate by opening a static pressure pocket to the piston shoe impulse surface of the swash plate at its passage, and positioning the passage to open and communicate to a cylinder chamber when the piston number at a high pressure area is (z+1)/2. CONSTITUTION:A control port 36 is provided on a valve plate 28 at the middle part of a high pressure port 29 and a low pressure port 30, and by giving a controlled pressure obtained by a two-position change-over valve 37 to the control port 36, the inclination of a swash plate 27 is changed. A static pressure pocket 33 is formed on the circular arc form of impulse surface 32 of the swash plate 27, and the passage 34 of the static pressure pocket 33 is opened to the piston shoe impulse surface of the swash plate 27. The passage 34 is positioned to be opened and communicated to a cylinder chamber 25 when the piston number at a high pressure area is (z+1)/2. As a result, the swash plate 27 can be moved obliquely by making the rolling friction moment small, and the separating force when the piston number at the high pressure area is (z+1)/2 is reduced, so as to prevent floating-up of the swash plate 27.

Title: Spring safety valve, safety valve system equipment and equipment fitting method
Inventor: KIYOTOKI YOSHIHISA
IPC: F16K17/168
Filed: 1989-12-06
Abstract: PURPOSE:To maintain safe performance by setting the thermal expansion coefficient of valve guide material larger than that of valve body material, thereby maintaining a clearance between the guide and valve body appropriately. CONSTITUTION:When a safety valve is in the totally closed state, a valve body 1 is heated directly by a high temperature fluid so as to generate thermal expansion. On the other hand, heat is transmitted to a guide 2 through a valve box 8, but because of the valve box 2 being cooled by atmospheric air, the temperature among the guide 2, the valve body 1 and a disc socket 1a differs, and a clearance deltaa between the guide 2 and the disc socket 1a of the valve body 1 is narrowed. However, as the thermal expansion coefficient of the material of the guide 2 is set to be larger than that of the material of the disc socket 1a, the clearance deltaa between both parties can be maintained appropriately, thereby maintaining safe performance.

Abstract: PURPOSE:To improve the operability of character input at title generation by adopting the title generating system combining a VTR and a personal computer. CONSTITUTION:When a keyboard 15 is operated to enter an optional desired character (a character within kinds of characters generated from a character generator 3 of a VTR 1), the character data is sent from a personal computer 14 to a microcomputer 2 of the VTR 1, the microcomputer 2 drives a character generator 3 to display the character inputted to a desired position on a screen 9a of a TV monitor 9. The character input operation is implemented sequentially by the operation of the character input key on a keyboard 15 and a cursor movement key and the character code data corresponding to the displayed character is sequentially stored in a character data memory 5. Thus, the character input is implemented by the key operation familiar with the user and the operability of the character input is improved.
